Why so many customers choose N42 neodymium rare earth magnets?
That’s because N42 neodymium magnets for sale is a great balance among cost, strength and performance under 80℃ operating temperatures. Although there are higher grades, such as N52 and N52, the max. working temperature is only 60℃. And not only the higher the grade, the stronger the magnet, but also the higher the grade, the higher the price.
Many strong magnet online retail stores also list more N42 neodymium permanent magnets on their websites. So N42 is perfect for green hands. For example, when you start a new project which need neodymium magnet and you don’t know What Grade Should I Choose, grade N42 neodymium rare earth magnet is a good start to have sample test. You can get the same strength as an N50 magnet by using a slightly larger N42 magnet or get the same strength as an N38 magnet by using a slightly small N42 magnet.But if you need the highest strength in the smallest possible size at room temperature, grade N52 or N55 is the strongest available.
Shape of Super Strong Neodymium N42 Magnet
N42 grade magnets can be made into many shapes, such as ring, disc, block, ball, arc, T shaped and other custom irregular shapes. Please magnet shape page for more information.
What does grade n42 magnet mean?
The grade N42 means neodymium magnet has a Maximum Energy Product of 42 MGOe. It refers to the maximum magnetic energy that the material can be stored. It can be showed by the magnet’s Demagnetization Curve, or BH Curve – the strongest point is (BH)max. Generally speaking, the higher the grade, the stronger the magnet. And currently, the highest grade of neodymium magnet available is N55, the lowest is N35.
What do grades N42M, N42H, N42SH and N42UH mean?
Compared with N42, N42M, N42H, N42SH and N42UH come with different letters. These grades following letters refer to the temperature rating of the sintered neodymium rare earth magnet. N42M is 100℃, N42H is 120℃, N42SH is 150℃ and N42UH is 180℃. Thereinto, N42SH high working temperature neodymium magnets are widely used on motor.
